Whether in the home or the workplace, social robots are going to become a lot more common in the next few years. Social robots are about to bring technology to the everyday world in a more humanized way, said Cynthia Breazeal, chief scientist at the robot company Jibo.

    While household robots today do the normal housework, social robots will be much more like companions(同伴) than mere tools. For example, these robots will be able to distinguish when someone is happy or sad. This allows them to respond more appropriately to the user.

    The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant. You can talk to the robot, ask it questions, and make requests for it to perform different tasks. The robot doesn't just deliver general answers to questions; it responds based on what it learns about each individual in the household. It can do things such as reminding an elderly family member to take medicine or taking family photos.

    Social robots are not just finding their way into the home. They have potential applications in everything from education to health care and are already finding their way into some of these spaces.

    Fellow Robots is one company bringing social robots to the market. The company's “Oshbot” robot is built to assist customers in a store, which can help the customers find items and help guide them to the product's location in the store. It can also speak different languages and make recommendations for different items based on what the customer is shopping for.

    The more interaction the robot has with humans, the more it learns. But Oshbot, like other social robots, is not intended to replace workers, but to work alongside other employees. “We have technologies to train social robots to do things not for us, but with us,” said Breazeal.

    In 1978, I was 18 and was working as a nurse in a small town about 270 km away from Sydney, Australia. I was looking forward to having five days off from duty. Unfortunately, the only one train a day back to my home in Sydney had already left. So I thought I'd hitch a ride (搭便车).

    I waited by the side of the highway for three hours but no one stopped for me. Finally, a man walked over and introduced himself as Gordon. He said that although he couldn't give me a lift, I should come back to his house for lunch. He noticed me standing for hours in the November heat and thought I must be hungry. I was doubtful as a young girl but he assured (使……放心) me I was safe, and he also offered to help me find a lift home afterwards. When we arrived at his house, he made us sandwiches. After lunch, he helped me find a lift home.

Twenty-five years later, in 2003, while I was driving to a nearby town one day, I saw an elderly man standing in the glaring heat, trying to hitch a ride. I thought it was another chance to repay someone for the favor I'd been given decades earlier. I pulled over and picked him up. I made him comfortable on the back seat and offered him some water.

    After a few moments of small talk, the man said to me, “You haven't changed a bit, even your red hair is still the same.”

    I couldn't remember where I'd met him. He then told me he was the man who had given me lunch and helped me find a lift all those years ago. It was Gordon.

    Japan has long been known for both its strong traditions and being on the cutting edge of technology, and this new inn combining the classic Japanese surroundings with high-tech slippers and furniture is a perfect reflection of this.

    Nissan Motor Co. developed a system in which slippers park themselves at the entrance of the traditional inn, called “ProPilot Park Ryokan,” waiting for guests to use them upon arrival. When guests have finished using them, the slippers will drive themselves back to their original position. Each slipper features two tiny wheels, a motor, and sensors to drive it across the wooden floor.

    The same technology features in Nissan's all-battery electric Leaf car. High-tech sensors and cameras allow the vehicle to safely back into parking spaces without any input from the driver. Four cameras and 12 sensors assess the vehicle's surroundings. ProPilot Park handles the accelerator, braking and steering (转向) input when the car is parking. Drivers operate the system with the press of a button, which they must hold down the entire time. Lifting a finger off the button will result in the car stopping immediately.

    The inn, located in the resort town of Hakone, about 75 kilometers southwest of Tokyo, is currently most famous for its view of Mount Fuji. However, the new self-driving slippers, released by Nissan in March, is the unique feature of the high-tech inn.

    “The self-parking slippers are meant to raise awareness of automated driving technologies, and their potential, non-driving applications,” Nissan spokesman Nick Maxfield said in a statement.

    In addition to the slippers, office chairs, floor cushions and traditional low tables in the inn also wheel themselves back into place after use.

    In some northern places, the cost of heating our homes boosts. Now millions of people are saving on their heating bills with the EP heater(加热器). With over one million satisfied customers around the world , the new EP heaters saves more heating bills, and runs almost silent.

    The EP has no exposed(暴露的) heating parts that may cause a fire. The outside of the EP only gets warm at the flick of a switch so that it will not burn children or pets.

    The EP will not reduce oxygen(氧气) in the room. With other heaters, you'll notice that you get sleepy when the heat comes on because they are burning up oxygen.

    The advanced EP also heats the room evenly, wall to wall and floor to ceiling(天花板). It comfortably covers an area up to 350 square feet. Other heaters heat rooms unevenly with most of the heat concentrated to the center of the room. And they only heat an area a few feet around the heater. With the EP, the temperature will not vary in any part of the room.

    The EP comes with a 3-year warranty(保修) and a 60-day, no questions asked, satisfaction guarantee. If you are not totally satisfied, return it at our expense and your money will be given back to you.

    Now we have a special offer for 10 days, during which you can enjoy a half price discount and a free delivery. If you order after that, we reserve the right to either accept or reject order requests the discounted price.

    Experts say there are about 6, 500 languages spoken throughout the world. But the United Nations estimates that about half of these languages are in danger of disappearing.

    One non-profit organization seeking to save world languages is a New York-based group called Wikitongues. Officials from Wikitongues say the organization has a simple goal: to provide the tools and support that people need to save their languages.

    Udell is the co-founder of Wikitongues. He said when a language disappears, many other things can go away as well. For example, parts of a community's culture, knowledge and identity can also be lost. Because of this. Udell believes the process of bringing languages back must be done by community members themselves, “from the ground up,” he said.

    “There is no way an outside organization can save someone's language for them.”

    Wikitongues was launched in 2016 as an open internet collection of world languages. The self-described “community” is operated by volunteers from around the world. The collection is in the form of language videos that people add to the Wikitongues website.

    There are currently more than 400 languages and dialects represented on Wikitongues' YouTube channel. Udell says more than 1,500 people from 70 different countries have added videos to the system.

    “We have people from India who record dozens of languages, which is beyond their own.” he said.

    One of Wikitongues'volunteers is Kolokwe, who lives in Namibia. His native language is Subiya, however, he does not get the chance to speak his native language every day. Like many other educated people from his area, he speaks a lot of English and Afrikaans.

    Kolokwe is hoping his involvement with Wikitongues call help keep Subiya and other African languages from going extinct. He wants the world to know about his language. But his goal goes beyond just sharing his language with others through video. He is also working to create a dictionary and language teaching materials that can be used in schools.

After a long and hard journey that made international headlines, China's famous herd of wandering elephants appears to finally be heading home.

In August, the 14 Asian elephants of various sizes and ages were guided across the Yuanjiang river in Yunnan and a path was being made for them to return to the nature reserve in the Xishuangbanna Dai Autonomous Prefecture.

The elephants' return completes a more than 500km odyssey that caught the attention of the country. The highlights of their trip included the birth of a calf in Pu'er in last November; and going viral for taking a nap. If they were just taking a walk in the forest, it wasn't a big deal. But the fact is, they left whatever they stepped on in ruins, causing great damage to local residents.

Local wildlife experts have been unable to pinpoint the reason the herd decided to move. One reason is given that the population of elephants in the nature reserve in the Xishuangbanna Dai Autonomous Prefecture is so large, which has increased from 190 to over 300 since 40 years ago, that there is not enough food for them. Some say that their move is due to the influence of the magnetic field of the earth and there is another story saying maybe that lead elephant lost its way, thus leading the herd out of the way. But Zhang Li, a professor on conservation biology at Beijing Normal University, told the Global Times in June that large-scale human engineering developments have sped up the ‘islanding'of elephant habitats.

This meant "the traditional safe zones between humans and elephants are gradually disappearing, and the chances of elephants encountering humans naturally increase greatly".
